Definition: Antievolutionary refers to a process or theory that suggests that life originated on Earth billions of years ago, before the modern evolutionary chain of events. This view posits that the earliest forms of life were composed of single cells or simpler units rather than complex organisms with DNA and other genetic material. Antivolutionary scientists argue this theory is supported by paleoanthropology and other historical evidence suggesting that early life on Earth was different from what we have today, leading to a lack of fossilized DNA, organ systems, and other features typical of modern life.
